4 1 HANDHELD FLUID COOLED ELECTRIC SOLDER TWEEZERS BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to electric solder tweezers, and more particularly, the present invention relates to hand held?uid cooled electric solder tweezers. 2. Description of the Prior Art Numerous innovations for handheld soldering devices have been provided in the prior art that Will be described. Even though these innovations may be suitable for the spe ci?c individual purposes to Which they address, however, they differ from the present invention. A FIRST EXAMPLE, US. Pat. No. 5,1,101 to BroWn et al. teaches a tweezer-type heating device for installation and removal of electronic components With respect to a substrate, such as for SMC installation and through hole installation or removal. More speci?cally, a handheld tweezer-type heating device is provided in Which a Wide variety of different sized (and shaped) tips can be used With a high degree of accuracy in terms of thermo/mechanical contact. Tolerances in the parts of the handpiece, the assembly, the heaters and the tips that may bring the bottom edges of the tips out of their alignment plane are very easily corrected With an adjustable hinge Which, by loosening of a screw and sliding the parts With respect to each other, allows proper alignment to be achieved. Still further, a thumb screw is provided at the back of the handpiece to allow the gap between the tips to be slightly opened or closed. This is useful in accommodating tolerances in the components. Also, it allows the operator to slip-?t the tips over the component and make proper thermo/ mechanical contact With little or no squeezing of the hand piece, thereby minimizing the chance of mechanically dam aging the component or its leads by squeezing too hard, or causing damage to adjacent components. A plate-like align ment tool With projecting tab portions that engages in an edge slot of the tip elements and contacts other surfaces of the tip elements, as Well, enables simultaneous aligning of the tip elements axially, laterally and rotationally With respect to each other and the mounting units. A SECOND EXAMPLE, US. Pat. No. 5,182,4 to Wang teaches an electric soldering iron that has an elongated hollow handle casing having a tubular hollow holder extending from one end thereof and supporting a soldering bit heated by an electric heater Within the holder. A forked suction pipe is secured to the holder and includes a main pipe having an intake port at one end disposed adjacent to the soldering tip and an outlet port at its other end connected to an induced draft fan assembly through a?exible air pipe. A branch pipe of the suction pipe extends laterally from the main pipe and has an intake port connected to the interior of the casing through a heat resistant hose. Actuation of the induced-draft fan causes soldering fumes generated at the tip to be drawn into the main pipe and for cooling ambient air to be drawn through the casing from an inlet at its other end to remove excess heat from the casing. A THIRD EXAMPLE, US. Pat. No. 5,796,072 to Okuno teaches an electric soldering iron that is made dif?cult to heat up at the front end of its grip. A metal pipe is inserted in the grip so that the pipe comes into close contact at least partially With the grip, With a gap formed between the outer peripheral surface of the pipe at its front end and the inner peripheral surface of the grip. The heat produced by the accumulator US 7,392,9 B conducts through the pipe to the grip and disperses through out the grip. Thus, the front tend of the grip is less likely to heat up. A FOURTH EXAMPLE, US. Pat. No. 5,909,5 to Cur Wick, et al. teaches a hot air torch for the Welding of plastic featuring an air?ow around and about the inner portions of tubular members Which entrains unwanted internally gener ated heat prior to the Welding tip to provide a torch body Which is safe to the touch While at the same time providing suitably heated air at the Welding tip. Excess accumulated heat is vented overboard in the vicinity of the Welding tip. A FIFTH EXAMPLE, US. Pat. No. 6,750,431 to Miyazaki teaches a tweezer-type hand-held device for removing an electric or electronic component from a substrate that is pro vided With a pair of contact pieces to be brought into contact With the component to grasp and heat the component and melt solder Which?xes the component on the substrate. The con tacts are respectively held by a pair of legs Which, in turn, are interconnected With each other such that one of the legs moves toward the other With the legs and contact pieces being kept in parallel With each other. A SIXTH EXAMPLE, US. Pat. No. 6,786,386 to Miyazaki teaches a soldering iron that comprises a tip end; a heater portion for electrically heating the tip end of the sol dering iron; a holding portion provided at the rear end of the heater portion: a heat pipe structure provided in the holding portion; a?rst heat pipe holder for holding a frontal portion of the heat pipe structure to Which heat generated at the heater portion is transferred; a second heat pipe holder for holding a rear part of the heat pipe structure; and a grip portion placed externally around the?rst heat pipe holder. It is apparent that numerous innovations for handheld sol dering devices have been provided in the prior art that are adapted to be used. Furthermore, even though these innova tions may be suitable for the speci?c individual purposes to Which they address, however, they Would not be suitable for the purposes of the present invention as heretofore described. SUMMARY OF THE INVENTION ACCORDINGLY, AN OBJECT of the present invention is to provide handheld?uid cooled electric solder tweezers that avoids the disadvantages of the prior art. ANOTHER OBJECT of the present invention is to provide handheld?uid cooled electric solder tweezers that is simple to use. BRIEFLY STATED, STILL ANOTHER OBJECT of the present invention is to provide a handheld?uid cooled electric solder tweezers. A pair of soldering heads extend from a pair of tweezer members, respectively, and are operatively con nected to a cooling apparatus. The cooling apparatus of each tweezer member includes a pair of heat dissipating tubes that travel in an associated tweezer member, With distal ends thereof in?uid communication With an associated soldering head, and With a proximal end of one thereof?uidly commu nicating With a?uid source. A crossover tube?uidly commu nicates the proximal end of one tube of one tweezer member With the proximal end of one tube of the other tweezer mem ber. The?uid source is preferably Water that enters and?ows through one tube of one tweezer member to and through an associated soldering head, then through the other tube of the one tweezer member, then through the crossover tube, then through one tube of the other tweezer member to and through an associated soldering head, then through the other tube of the other tweezer member, and back to the?uid source so as to form a closed loop, and in doing so, cools the pair of tweezer members.

The overall con?guration of the handheld?uid cooled electric solder tweezers 10 can best be seen in FIG. 2, Which is a reduced exploded diagrammatic perspective view of the area generally enclosed by the dotted curve identi?ed by ARROW 2 in FIG. 1 of the handheld?uid cooled electric solder tweezers of the present invention, and as such, Will be discussed With reference thereto. The handheld?uid cooled electric solder tweezers 10 com prise a pair of tweezer members 12, a cooling apparatus 14, a pivoting apparatus 16, and a pair of soldering heads 17. The pair of tweezer members 12 are pivotally attached to each other. The cooling apparatus 14 is operatively connected to, and cools, the pair of tweezer members 12. The pivoting apparatus 16 pivotally attaches one tweezer member 12 to the other tweezer member 12. The pair of soldering heads 17

6 5 extend from the pair of tweezer members 12, respectively, and are operatively connected to the cooling apparatus 14. The pivoting apparatus 16 comprises a pivot pin 18, a?rst resilient band, and a second resilient band 22. The pivot pin 18 of the pivoting apparatus 16 pivotally attaches one tweezer member 12 to the other tweezer member 12, is generally cylindrically-shaped, and has a pair of ends 24. Each end 24 of the pivot pin 18 of the pivoting apparatus 16 has a blind slot 26 extending transversely thereacross. The?rst resilient band of the pivoting apparatus 16 is generally rectangularly-shaped, extends around the pair of tweezer members 12 to maintain the pair of tweezer members 12 against the pivot pin 18 of the pivoting apparatus 16, and seats in the blind slot 26 in each end 24 of the pivot pin 18 of the pivoting apparatus 16 to maintain itself in place. The second resilient band 22 of the pivoting apparatus 16 is generally rectangularly-shaped, extends around the pair of tweezer members 12 to adjust biasing of the pair of tweezer members 12, and is more resilient than the?rst resilient band of the pivoting apparatus 16. The speci?c con?guration of each tweezer member 12 can best be seen in FIGS. 3 and 4, Which are, respectively, an enlarged exploded diagrammatic perspective view of the area generally enclosed by the dotted curve identi?ed by ARROW 3 in FIG. 2 of one tweezer member of the handheld?uid cooled electric solder tweezers of the present invention, and an enlarged diagrammatic cross sectional view taken along LINE 4-4 in FIG. 2 showing the cooling?uid?ow through one tweezer member of the handheld?uid cooled electric solder tweezers of the present invention, and as such, Will be discussed With reference thereto. Each tweezer member 12 comprises a body 28, one solder ing head 17, and a portion of the cooling apparatus 14. The body 28 of each tweezer member 12 is slender, elon gated, and has a generally channel-shaped lateral cross sec tion, a proximal end, a distal end 32, and an intermediate point 34 that is intermediate the proximal end thereof and the distal end 32 thereof. The body 28 of each tweezer member 12 has a channel 36 therealong, a pair of connecting edges 37, and a Web 39, as a result of the channel-shaped lateral cross section thereof. The channel 36 of the body 28 of each tweezer member 12 face each other. The intermediate point 34 of the body 28 of each tweezer member 12 is formed into a recess 41. The recess 41 of the intermediate point 34 of the body 28 of each tweezer member 12 is generally semi-circular-shaped and pivotally receives the pivot pin 18 of the pivoting apparatus 16. Each connecting edge 37 of the body 28 of each tweezer member 12 has at least three notches therein. A forward most notch in the pair of connecting edges 37 of the body 28 of each tweezer member 12 aligns With the blind slot 26 in each end 24 of the pivot pin 18 of the pivoting apparatus 16 and receives the?rst resilient band of the pivoting appa ratus 16 to further maintain the?rst resilient band of the pivoting apparatus 16 in place. Remaining notches in the pair of connecting edges 37 of the body 28 of each tweezer member 12 are disposed rear Ward of the forwardmost notch in the pair of connecting edges 37 of the body 28 of an associated tweezer member 12 and selectively receive the second resilient band 22 of the pivoting apparatus 16 to adjust biasing of the pair of tweezer members 12. The body 28 of each tweezer member 12 further has a stop 42. The stop 42 of the body 28 of each tweezer member 12 extends inwardly into the channel 36 in the body 28 of an associated tweezer member 12 and towards each other and is US 7,392,9 B disposed forward of the pivot pin 18 of the pivoting apparatus 1 6 to limit pivoting of the pair of tweezer members 12 relative to each other. The stop 42 of the body 28 of each tweezer member 12 is generally cylindrically-shaped and is a?ixed to the Web 39 of the body 28 of an associated tweezer member 12 by a screw 44 passing through an external Washer 46, through a bore 48 in the Web 39 of the body 28 of the associated tweezer mem ber 12, through an internal Washer 50, and threadably into the stop 42 of the body 28 of the associated tweezer member 12. The soldering head 17 of an associated tweezer member 12 extends forwardly from the distal end 32 of the associated tweezer member 12 and is in electrical communication With a power source interface 52 for electrically communicating With a power source 54. The power source interface 52 of each soldering head 17 is a Wire 56 having a proximal end 58 and a distal end 60. The Wire 56 of the power source interface 52 of each soldering head 17 travels in the channel 36 of the body 28 of an asso ciated tweezer member 12, With the distal end 60 thereof in electrical communication With an associated soldering head 17, and With the proximal end 58 thereof for electrically communicating With the power source 54. Each soldering head 17 is generally channel-shaped in lateral cross section so as to form a channel 62 therein With a pair of?anges 63 and has a soldering tip 64 received in the channel 62 in the associated soldering head 17. The distal end 60 of the Wire 56 of the power source interface 52 of each soldering head 17 has a screw 66 passing therethrough that then passes through a bore 68 in one?ange 63 of the channel 62 of an associated soldering head 17, then through a through bore 70 in the soldering tip 64 of the associated soldering head 17, then through a bore 72 in the other?ange 63 of the channel 62 of the associated soldering head 17, then through a Washer 74, and threadably into a nut 76. The cooling apparatus 14 of each tweezer member 12 comprises a pair of tubes 78 that are heat dissipating and have proximal ends 80 and distal ends 82. The pair of tubes 78 of the cooling apparatus 14 of each tweezer member 12 travel in the channel 36 of the body 28 of an associated tweezer mem ber 12, With the distal ends 82 thereof in?uid communication With an associated soldering head 17, and With the proximal end 80 of one thereof for?uidly communicating With a?uid source 84. As shown in FIG. 5, Which is a diagrammatic top plan view taken generally in the direction of ARROW 5 in FIG. 1, rotated 180 degrees showing, the cooling?uid?ow through the handheld?uid cooled electric solder tweezers of the present invention. The cooling apparatus 14 further com prises a crossover tube 86. The crossover tube 86 of the cooling apparatus 14 is?exible and?uidly communicates the proximal end 80 of one tube 78 of one tweezer member 12 With the proximal end 80 of one tube 78 of the other tweezer member 12. Fluid, Which can be a gas or a liquid, such as Water and the like, from the?uid source 84 enters and?ows through one tube 78 of one tweezer member 12 to and through an associ ated soldering head 17, then through the other tube 78 of the one tweezer member 12, then through the crossover tube 86, then through one tube 78 of the other tweezer member 12 to and through an associated soldering head 17, then through the other tube 78 of the other tweezer member 12, and back to the?uid source 84 so as to form a closed loop, and in doing so, cools the pair of tweezer members 12.
